不同微波功率下微藻、海藻和油页岩热解特性对比研究

摘要

利用微波反应器,研究了不同微波功率下微藻(小球藻)、海藻(马尾藻)和油页岩的微波热解特性.结合能量消耗和能量输出的评价方法,对比分析了微藻、海藻和油页岩微波热解三相产物的单位电耗产量.结果表明:750 W时,海藻的产油量和产气量最大;1500 W时,微藻的产油量最大,海藻的产气量最大;2250 W时,微藻的产油量和产气量最大;从单位电耗产油量的角度来看,微波热解微藻、海藻和油页岩的合适功率分别为1500,750 W和2250 W;微藻、海藻和油页岩的单位电耗产油量和单位电耗产气量之和分别为44.199,41.987 g/(kW·h)和13.081 g/(kW·h),微藻和海藻的能源价值远大于油页岩.%The pyrolysis characteristics of microalgae (Chlorella), seaweed (Sargassum) and oil shale under different microwave power were studied by microwave reactor. The absolute productivity of microwave pyrolysis three - phase products of microalgae, seaweed and oil shale was compared and analyzed by the energy consumption and energy output. The results show that the maximum amount of oil production and gas production is seaweed at 750 W; The maximum amount of oil is the microalgae, and the maximum amount of gas is seaweed at 1 500 W; The oil production and the largest amount of gas are microalgae at 2 250 W; From the perspective of unit power consumption of oil production, microwave pyrolysis microalgae, seaweed and oil shale of the appropriate power were 1 500, 750 W and 2 250 W; The sum of unit fuel consumption and unit power consump tion per unit of microalgae,seaweed and oil shale were 44.199, 41.987 g/(kW·h) and 13.081 g/(kW·h),the energy value of microalgae and seaweed is much larger than the oil shale.
